To all whom it may concern:

Be it known that I, BERNHARD COHNEN, a subject of the Emperor of Germany, and a resident of Grevenbroich, Rhenish Prussia, and Empire of Germany, have invented certain new and useful Improvements in Apparatus for Sizing and Dressing Yarn, of which the following is a specification, this invention having been patented to me in Germany, No. 86,794, dated November 5, 1895, and No. 92,427, dated July 24, 1897; in France, No. 250,451,dated September21, 1895; in Belgium, No. 117,624, dated September 26, 1895; in Italy, R. A. 275, dated June 27, 1895; in Austria-Hungary, No. 20,668 and No. 20,669, dated November 2, 1895, and in Great Britain, No. 23,993, dated October 28, 1896. f

The invention is illustrated in the accompanying drawings, in which- Figure 1 represents a sectional front elevation of my improved apparatus. Fig. 2 is an end View of the same. Fig. 3 shows a modification of one of the parts of my improved apparatus. Fig. 4 is an end view of Fig. 3.

Upon an axle a, carried in bearings in a suitable frame a, are keyed two spider-wheels b b. The spider-wheels Z) I) carry in fixed bearings a series of six rollers c c c c c c. In connection with each roller is another roller 0 f f f f f f which rollers are carried by means of a chain 01.

and revolve in bearings formed in arms g g g g g g, loosely pivoted to the spider-wheels. These pairs of rollers c and fare preferably of seamless copper and carry the yarn to be sized. Any convenient number more or less than six such pairs of rollers may be employed.

The rollers f, carried by the pivoted arms 9,

can be moved toward the rollers c. The hanks of yarn are laid on the pairs of rollers c f, springs h, located between the arms and adjacent portions of the spider-wheels, acting to stretch the yarn. The rollers c are pro- Vided with chain-wheels d and are driven by The chain d also drives The sleeve a carries a fast and a loose pulley i i and is also provided with a chain-wheel communicating motion by means of a chainto the chain wheel j. (See Fig. 2.) The chainwheel j is carried by a short shaft is, revolving in suitable bearings in the frame of the machine. The other end of the short shaft carries a chain-wheel Z, meshing with the chain 61. Motion is thus communicated from the fast pulley 1' to the chain (1.

The action of the apparatus is as follows: The outer spider-wheel b is provided with six notches, more or less, corresponding to the number of pairs of rollers employed, with which a hinged bolt 6 is adapted to engage. Motion having been imparted to the fast pulley t', the attendant disengages the hinged bolt e fromthe notch. The chain d then revolves the spider-wheels b b and with them the pairs of rollers c f until one-sixth of a revolution is effected, when the hinged bolt drops into the next notch, and the spiderwheels I) are thus stopped. The chain, however, continues its motion and on the stoppage of the spider-wheels]; revolves the rollers 0 upon their axes. As the yarn is stretched upon the rollers of by the action of the spring h the revolution of the rollers 0 sets the yarn and also the rollers f in motion. From an inspection of Fig. 1 of the drawings it will be seen that during the stoppage of the spiderwheels I) b the yarn on the pairs of rollers c f c f is being immersed in the size contained in the trough m. The size is pressed into the hanks by means of two fluted wooden squeezing-rollers n n, one of which is immersed in the size, while both work against the copper rollers. The yarn is thus perfectly saturated without being in any way disturbed or entangled. The yarn upon the rollers c f having been immersed in the size, is subjected to the squeezing action of a rubber-covered roller 4", carried in bearings in levers r, pivoted to the frame of the machine.

Adjusting-screws r are provided to regulate the pressure of the roller r upon the yarn, and thus determine the amount of size to be left in the yarn.

Upon the pairs of rollers 0 c f the yarn is brushed and opened out over the whole width of the rollers. This is effected by means of revolving combs or card-covered rollers 0 0, upon which is spirally arranged card-clothing or other similarly-needle-pointed material, which acts upon the yarn after the manner of temple-rollers in a loom. The card-clothing or other needle-pointed material acting upon the yarn carried by the rollers c f is arranged at an angle contrary t2 that operating upon the yarn on the rollers c f but are revolved by the passage of the yarn itself. The yarn upon the rollers 0 f having previously passed through these successive operations of sizin g,squeezin g, and brushing, is ready to be doffed from the rollers. To effect this in safety, it is essential that the rollers c f should be at rest. At this part of the machine therefore the chain 01' does not engage with the chain-wheel upon the roller 0 but is led over carrying-wheels d (Shown in dotted lines in Fig. 1.) The operator therefore by advancing the roller f toward the roller 0 as shown in dotted lines, can quickly remove the sized and dressed yarn and replace it with another hank. The bolt 9 is then released and the spider-wheels b bare again revolved one-sixth of'a revolution, and the cycle of operations is repeated.

As the chain d is constantly driven, it will be seen that it alternately revolves the spiderwheels and the rollers c. For the purpose of maintaining the size in its proper condition and free from threads, lumps, and other foreign matter it is caused to circulate through a straining-tank p by means of a pump q, as indi'cat'edin Fig. 2.

The trough m is formed with a steam-heated chamber m to maintain the size at any suitable temperature.

In Figs. 3 and 4 of the drawings Ishow a modification of the means for stretching the yarn upon the rollers and. also automatic means of traversing the roller f toward and from the roller 0 when the sized and dressed hank is to be doffed and replaced by another hank. To effect this, I provide the frame of the machine with a cam-groove s. This camgroove is shown in front view in Fig. 3,while Fig. 4 is an end view of Fig. 3. The rollers f are carried, as before, by arms provided with bearings in the spider-wheels b b, and in addition are provided with rigidly-connected arms 25, forming with the arms carrying the rollers bell-crank levers. The lower ends of the rods t are provided with antifriction-bowls t, running in the cam-groove s. For about three-quarters of the circumference of the cam-groove s the cam-groove is concentric and maintains the two rollers o f sufficiently apart to impart the desired tension to the yarn. As the rollers c f approach the doffing position in the machine the bowl t on the end of the rod 25, following the contour of the camgroove, operates the roller f, so as to automatically bring the same nearer to the roller The rollers o are not positively driven, I

c, as shown in the diagram Fig. 3. Instead of a rigid connecting-rod i I might use a flexible connection and bring the rollers together at the required times by means of a spring 25 as indicated in dotted lines.

On the stoppage of the machine the operator doffs the yarn, replaces it with a fresh hank and again starts the machine, when the cam-groove s operates to gradually stretch the yarn before the same is immersed in the sizing-trough.

In order to lift the card-rolls 0 O and prevent them from coming in contact with the yarn-carrying cylinders, cam-tracks m are provided,carried by one of the spiders,located as shown in Fig. 3.

The card-rolls are journaled in arms 0 carried by rook-shafts O journaled in the frame of the machine. These rock-shafts carry also gear-segments X, which mesh with each other, so that they are thus caused to move simultaneously. An arm m, extending from one, carries a weight :3 which tends to hold the card-cylin der depressed,while an arm 00 secured to the other rock-shaft, carries a roller w, adapted to come in contact with the cam-tracks m, and thus raise the card-rolls out of the path of the cylinders c f.

I declare that what I claim is- 1. In a hank-sizing machine comprising the tank, the rotary frame, the set of cylinders journaled in said frame, the second set of cylinders journaled in movable bearings and adapted to be moved toward and from the first set to permit the insertion and removal of the hanks, and means for intermittingly rotating the frames and for rotating the cylinders when the frames are stationary, substantially as described.

2. In combination, the tank, the rotary frame, the set of cylinders journaled in said frame, the second set of cylinders journaled in bearings movable toward and from the first set of cylinders, means for i ntermittingly rotating the frame, and for rotating the first set of cylinders during the period when the frames are stationary, and means for holding the movable cylinders away from the first set of'cylinders during the major portion of the rotation of the frame and for bringing them into proximity to permit the removal of the sized hanks and the supplying of fresh ones to the cylinders, substantially as described.

3. In combination, the tank, the rotary frame, the set of cylinders journaled therein, the sprocket-wheels carried by the shafts of said cylinders, the sprocketchain passing over said wheels and over an idler-wheel serving to hold the chainremoved at one point in the path of said sprockets as the frame rotates, the second set of cylinders movable toward and. from the first set, means for driving said sprocket-chain torotate the frame, and means for holding the frame stationary while the movement of the chain continues whereby the cylinders are rotated, substantially as described.

- rotation of the frame, substantially as described.

5. In combination, the tank, the rotary frame, the set of cylinders journaled therein, the second set of cylinders journaled in bearings movable toward and from the first set, said first and second sets being arranged in pairs to carry the hanks to be sized, means forintermittingly rotating the frame and for rotating the cylinders when the frame is stationary, the rocking arms carrying cardingrolls, quadrants carried by the shafts of said rocking arms to cause their simultaneous movement, an arm carried by one of said shafts, and cams carried by the rotary frame adapted to lift-said arm to remove the carding-rolls from the path of the cylinders, substantially as described.
